Play Tetris on the Pumpktris
If it seems like all the kids in your neighborhood have grown up and you spend most of Halloween night standing around waiting for trick-or-treaters to knock, just do what Nathan Pryor did and carve a fully-functional Tetris game into your pumpkin. In addition to carefully drilling and carving out square holes for all 128 LEDs used to create the pixelated display, Pryor managed to camouflage all of the other electronics inside, and even turned the pumpkin’s stem into a functional joystick for actually playing the game.
